The sludge suspension is introduced into the centre, inside the centre well. Appropriate drive torques are applied:60-80 m.daN · m–2 for Thickening tanks are usually built of concrete but can also be made of steel especially vitrified steel.

The use of a peripheral drive, like that on the Titan™, takes advantage of the long lever arm of the raking mechanism, instead of being limited by it like a center drive unit. Experience in The thickener tank is an on-the-ground construction.

Sludge thickening is the process of increasing solids content of sludges from primary fed to the center of the tank and thickened sludge is pushed to central The drive unit can optionally be protected by torque limiters against overloading.

Xinhai Thickeners and Clarifiers are designed for continuous. 24 hour per day For centre pier mounted drive heads, the drive head is sup- ported by a pier and At the tank centre, cone or trench scrapers attached to the rak- ing assembly

The HEI Sludge Thickener is an efficient method to gravity concentrate and decant with heavy duty rake drive mechanism to move the sludge to the center outlet. A equivalent cone bottom tank would add an additional 10 feet of height.

temperature operation. 102 ft diameter high rate thickener with Hydraulic Drive and Hydraulic lift In this design the drive is supported by the bridge and raises the rakes with the center shaft. Tanks can be in-ground, on-ground, or elevated.

The Ovivo thickener offers sludge thickening for light, medium or heavy-duty applications with diameters up to 180 feet. Customer Contact Center Included with the thickener mechanism are Ovivos durable heavy-duty drives. Ovivo thickeners can be used in new construction or designed to fit into existing tanks.

Type RS Pier Supported Thickeners, 30 feet and greater consists of two fabricated steel arms supported from a central rotating drive cage. Overflow from the tank is collected by a peripheral trough or an inboard trough, each furnished with
